MemoraDB is a high-performance in-memory database (IMDB) designed for ultra-low latency key-value storage and operations, featuring RESP protocol compliance, atomic commands, and TTL-based expiry. Optimized for microsecond response times, it's ideal for real-time applications like caching and session stores.

A simple Redis clone implemented in Go

Rust Memory Cache is a TCP simple single thread memory cache developed in Rust using RESP Protocol.

In-memory key–value store with LRU eviction, hash–list indexing, sustaining <10µs access latency and persistent retrieval at ~1–2ms, epoll-based TCP server handling 10K+ concurrent connections with the RESP-2 protocol for scalable client–server communication. Benchmarked extensively via redis-benchmark achieving 92K GETs/sec and 84K SETs/sec .

Tiny redis with RESP protocol decoding/encoding, RDB persistance, replication, sreams and transactions support

lite version of redis

Embedded Redis Server is a lightweight, in-process Redis-compatible server written in Kotlin. Designed for testing, development, and CI/CD pipelines. Features Spring Boot auto-configuration, RESP2 protocol support, and zero external dependencies. Use it just like H2 Database - simply add the dependency and start coding!

A simple redis-compatible asynchronous in-memory key value store.

A multi-threaded, persistent Key-Value store in Go. Features a custom RESP parser, fine-grained concurrency (RWMutex), and sustains 440k+ req/s in benchmarks
